A large scale interface multi-fluid model for simulating multiphase flows

A spectrally refined interface approach for simulating multiphase flows

This paper presents a novel approach to phase-interface transport based on pseudo-spectral sub-grid refinement of a level set function. In each flow solver grid cell, a set of quadrature points is introduced on which the value of the level set function is known. This methodology allows to define a polynomial reconstruction of the level set function in each cell. The transport is performed using...

Control of Interface Evolution in Multiphase Fluid Flows

Parallel Computing Techniques for Large-Scale Reservoir Simulation of Multi-Component and Multiphase Fluid Flow

Massively parallel computing techniques can overcome limitations of problem size and space resolution for reservoir simulation on single-processor machine. This paper reports on our work to parallelize a widely used numerical simulator, known as TOUGH2, for nonisothermal flows of multicomponent, multiphase fluids in three-dimensional porous and fractured media. We have implemented the TOUGH2 pa...

A Practical Desalinization Model for Large Scale Application

Salinity of soil and water is the most important agricultural hazard in arid and semi-aridregions. In saline soils, yield production directly influences by soluble salts in the root zone aswell as by shallow water table depth. The first step for reclamation of such soils is reducingsalinity to optimum level by leaching. The objective of this study was to develop a practicalmodel to estimate wat...

Multi-scale modeling of compressible multi-fluid flows with conservative interface method

One important issue associated with the complexity of dynamically evolving material interface is the scale-dependent dynamics which implies very different physical phenomena depending on the resolvability of the material interface. In this work we present a concept of multi-scale modeling where the interface interaction is modeled as being in mechanical non-equilibrium or in equilibrium, depend...
